BOILER-FURNACE.

SPECIFICATION formin art of Letters Patent No. 629,606, dated J'uly 25, 1899.

7 Application filed November 29, 1898. Serial No. 697,740. N modeL To alt whom it ntcty concern.-

Be it known that I, ANDRE PANAYOTTI RIT- ZOS, of Galata, Constantinople, Turkey, have in vented a new and Improved Boiler-Fu rnace, of which the following isa full, clear, and exact description.

The object of the invention is to provide a new and improved boiler-furnace which is simple and durable in construction, very effective in ope-ration, and arranged to utilize the fuel economically and to the greatest advantage to insure quick heating of the water and a consequent generation of steam.

The invention consists of novel features and parts and combinations of. the same, as will be'fully described hereinafter and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a cross-section of the same on the line 2 2 in Fig. 3. tudinal sectional elevation of the same on the line 3 3 in Fig. 4, and Fig. 4: is a sectional plan view of the same on the line 44 in Fig. 3. The improved boiler-furnace is provided with the usual brickwork A, lined with firebrick B, and formed with a suitable fire-box O and a combustion-chamber D immediately in the rear of said fire-box and somewhat wider than the latter, as plainly indicated in Fig. 4. In the fire-box O is arranged a grate E, below which is an ash-pit O, and the fuel is discharged upon said grate E over an inclined grate E, connected at its upper forward end with a chute F, leading to a fillingdoor G at the front of the furnace. By the arrangement described the fuel introduced through the filling-door slides down the chute F, upon and over the grate E, and down upon the grate E to be turned thereon. The ashes are removed from time to time from the ashpit G through a door G at the front of the furnace.

In the combustion-chamber D are arranged water-heating elements H H H located one behind the other and each made in sections, similar to ordinary steam or hot-Water radi: ators, the sections being preferably almondshaped and connected at top and bottom,

Fig. 3 IS a long1- 1 the long axis extending longitudinally in line withthe travel of the smoke and gases passing from the fire-box 0 through the combustion-chamber D, as hereinafter more fully described.

, The front heating element H has its sections connected with each other'by a verticallydisposed wall H extending from the bottom of the combustion-chamber to near the top of the element, sothat the smoke and gases arising from the burning fuel in the fire-box G cannot pass between the sections of the front element, but have to pass upward into the top of the combustion-chamber and then travel downward between the sections of the elements 11 H to finally reach the outlet J, leading from the bottom of the combustionchamber, at the rear endthereof, to a chimney or other device for carrying off the products of combustion. The elements H H H are connected with suitable pipes I for circulating the water and for carrying off the steam generated upon heating the water. The elements are of diiferent height, and, as illustrated, the one adjacent to the fire-box O is the highest and theone adjacent to theout- .let J the lowest. The elements thus project upwardly one beyond the other, so that the upper portion of each is better exposed and will come in contact with the current of hot gases. It will be understood that the walls H prevent the hot gases from passing between the sections of the element H and compel them to pass upwardly along the front face of said element and then rearwardly over the top thereof. After passing over said walls H however, the hot gases can pass between the sections of the elements H H since said sections are spaced and not connected by walls, such as H.

In the rear end of the brickwork A and firetage for raising the temperature of the water circulating through said heating elements. By giving the sections of the heating elements the shape described solid matter is not liable to lodge on said sections, and consequently said heating elements are not covered by non-heat-conducting material. The heating capacity of the furnace is, therefore, not decreased during constant use.

Having thus fully described my invention,

I claim as new and desire to secure by Letters cated one behind the other in said combustion-chamber and projecting upwardly one beyond the other, the front element being formed with a transverse wall reaching from the bottom of the combustion-chamber up ward to nearly the top of the element, the top of the latter being a distance from the roof of the fire-box, substantially asshown and described.

3. A boiler-furnace, comprising a fire-box, a combustion-chamber having an outlet in its rear end, and a series of heating elements located one behind the other in said combustion-chamber and projecting upwardly one beyond the other, the front element being formed with a transverse Wall reaching from the bottom of the combustion-chamber upward to nearly the top of the element, the top of the latter being a distance from the roof of the firebox, and the rear elements being made in sections, spaced apart for the pasa combustion-chamber having an outlet in its rear end, and a series of heating elements located one behind the other in said combustion-chamber and projecting upwardly one beyond the other, the front element being formed with a transverse wall reaching from the bottom of .the combustion-chamber upward to nearly the top of the element, the top of the latter being a distance from the roof of the fire-box, the rear elements being made in sections, spaced apart for the passage of the smoke and gases in a downward direction to the said outlet, and the sections of the elements being made almond-shaped in crosssection, the longitudinal axis of the elements standing in alinement with the travel of the smoke and gases from the fire-box to said outlet, substantially as shown and described.

5. A furnace comprising a fire-box, a coinbustion-chamber having an outlet at the opposite end to that connected with the fire-box, and a series of heating elements located one behind the other in said combustion-chamber and projected upwardly one beyond the other, the front element consisting of spaced sections and transverse walls connecting the adjacent sections so as to form therewith a barrier preventing the hot gases from pass ing between said sections, while the other elements consist of sections separated by unobstructed spaces so that the hot gases can pass freely between the sections of said other elements.
